5.2.3 Check the voltage on the power supply signal wire
If the high voltage or low voltage of the power supply is OK, but the CHECK
light still flashes, you should check the voltage on the power supply signal
wire with ohmmeter (Fig. 5.2.3-1). It should read close to 1.3V dc, if not, try
to replace the wire and check again. If the reading still shows less than 1.3V
dc or zero, the C10 resistance is damaged, you will need to replace the high
voltage supply ( See
3.3 HIGH VOLTAGE POWER SUPPLY AND UNIT
POWER CONTACT BOARD
).
5.2.4 Check the discharge switch
If the CHECK light still flashes, you also need to check the discharge switch.
- Unplug the discharge switch low voltage wire connection from the unit low
voltage contact terminal (Fig. 5.2.4-1).
-
Try to start the unit. If the CHECK light does not flash, the discharge switch
is damaged, you will have to replace or repair it. See
6.5 REPLACE THE
DISCHARGE SWITCH
.
Fig. 5.2.4-1 Unplug the discharge switch low
voltage black wire connection and to operate
the unit. If the CHECK indicator light stops to
flash, replace the discharge switch. When the
switch voltage wire is disconnected, the switch
does not work.
Fig. 5.2.3-1 Check the voltage on the power
supply signal wire. It should read close to
1.3V dc.
